@abstract(Provides Microsoft Macro Assembler (MASM) highlighter for SynEdit)
@author(Thomas Jaeger <thomasjaeger@gmail.com>)
@created(February 12th, 2017)
@lastmod(February 12th, 2017)
The SynHighlighterASM unit provides SynEdit with a Microsoft Macro Assembler (MASM) highlighter.
The highlighter supports all MASM features including directives and macros.

May experience out of memory when compiling package. Folow instructions to
compile externally until I move the API functions externally into JSON file.
