co⚡e: Sparkplug™ MQTT edge

Added 1 test in FunctionTestSuite (passes)
Added several visual updates

branched from trunk:
mqttsparkplug-unittest

Deleted branches develop mqttsparkplug-unittest

[#90] 1.4.2.24 Added unfinished FB_Property, which can be registered with an FB_Metric

[#90] 1.4.2.23 Added IProperty and IPropertyOwner
Fixed Copmile error in ClaimNextFreeKey

Added a fully functioning webvisu to view testresults via webserver next to xUnit type report.

Added yet more test skeletons/code from old unittests

[#90] 1.4.2.22 An FB_Payload can now dynamically create (PropertySet) Keys
Need now:
* an FB_Property, with factory, which can be registered to an FB_Metric.itfMetric
* testing

also added the ability to dynamically create (Dataset) Columns

[#90] 1.4.2.21 An FB_Payload can now dynamically create FB_PayloadPropertySetValue(s)
Need now:
* a LinkedListWStringElementFactory for the PropertySetKeys
* an FB_Property, with factory, which can be registered to an FB_Metric.itfMetric
* testing

Added various tests allthough they still need to pass as lib needs debugging

All new testrig setup for unittest of coBolt using TEST_ORDERED() functionality.

[#144] continue work towards FB_WStringBuilder larger string size
Append, Delete, Find, InsertAt have been modified
No testing done yet
The other methods still can be checked

[#138] Fixed missing seqNums v1.4.2.19

NDATA_publish was immediately exited, and the next publish does not wait and receives the DONE flag of the previous publish.

Sparkplug Development Lib v1.4.2.18 changelog, still work in progress
* changed Project Information

* Changed FB_MetricFileTransfer.ReturnFileName (Maybe it should return the filetransfer properties (filesize, filename, full path, any other metadata on the file?)

* Changed FB_StringBuilder as preliminary unittesting shows it contains bugs
regarding WSTRING(80) which is nonsensical for WSTRING

* FB_StringBuilder main body
* FB_StringBuilder.append
* FB_StringBuilder.delete
* FB_StringBuilder.find
* FB_StringBuilder.insertat
* FB_StringBuilder.len
* FB_StringBuilder.mid
* FB_StringBuilder.replaceat
* FB_StringBuilder.right
* FB_StringBuilder.tostring
* FB_StringBuilder.towstring
* Changed ILimitedStringBuilder, EXTENDS __SYSTEM.IQueryInterface
* Changed IStringBuilder, EXTENDS ILimitedStringBuilder
* Added Function ReturnFileName as this function seems to be useful enough
* Added accompanying unittest for FB_StringBuilder in seperate project, also work in progress

New setup for unittest, integrationtest and user pov test for co⚡e - Sparkplug™ MQTT edge and host
Reorganised project into at least 3 folders:
* unittest
* integrationtest
* user pov test.

Skeleton template demonstrated in unittest == Stable and ready
Added tests for FB_WStringBuilder

v1.4.2.17 Started implementation of
FB_MetricFileTransfer

Branch v1.4.2.16
introduces FB_FileControl
and IFileTransfer
for the yet to be written FB_MetricFileTransfer

[#134] Library is now displayed even if "show advanced libraries" is not selected
added Application|Utils to library categories

v1.4.2.14
* Added FB_SeqCheck with methods: BDSeqNum and SeqNum
* Updated Project Information to enable documentation generation

v1.4.2.13 example project

[#138] [#137] v1.4.2.13 Fixed missing DBIRTH and Edge Publish Rates

example for 1.4.2.12
- all additional libraries are now in POUs view
- Primary Host now uses the scenario selected in POUs View
- Primary Host now no longer needs user to add Blank Groups nor edges nor devices nor metrics

v1.4.2.12 Library now uses FBFactory to create GroupIDs, RemoteEdges, RemoteDevices and Metrics
You now no longer need to add GroupID, Edge, Device and metric pools in the user project of the PrimaryHost

Finally an example for v1.4.2.11 which is "up to par"

poof -> gone
