Abstracting some non-UI logic from FastMMUsageTracker.pas into a separate unit.

MemoryManagerUnit.pas

This abstracts some non-UI logic from FastMMUsageTracker.pas.

Please shoot at it and the example.

I have implemented the .ToString methods using JSON, using extra classes because built-in Delphi JSON support has no easy way to convert a record to JSON and the base types (either in the System or FastMM4 unit) are record based.

There is some fiddling with record helpers so it works in FastMM and regular mode.

unit MemoryManagerUnit;
// based on ideas in https://stackoverflow.com/questions/437683/how-to-get-the-memory-used-by-a-delphi-program/437749
