.SYNOPSIS
    Objective-C Language Definition.
.DESCRIPTION
    Allows PipeScript to generate Objective C/C++.

    Multiline comments with /*{}*/ will be treated as blocks of PipeScript.

    Multiline comments can be preceeded or followed by 'empty' syntax, which will be ignored.

    The Objective C Inline Transpiler will consider the following syntax to be empty:

    * ```null```
    * ```nil```
    * ```""```
    * ```''```

    $FilePattern = '\.(?>m|mm)$'
    # We start off by declaring a number of regular expressions:
    $startComment = '/\*' # * Start Comments ```\*```
    $endComment   = '\*/' # * End Comments ```/*```
    $Whitespace   = '[\s\n\r]{0,}'
    # * IgnoredContext ```String.empty```, ```null```, blank strings and characters
    $IgnoredContext = "(?<ignore>(?>$("null", "nil", '""', "''" -join '|'))\s{0,}){0,1}"
    # * StartRegex ```$IgnoredContext + $StartComment + '{' + $Whitespace```
    $StartPattern = "(?<PSStart>${IgnoredContext}${startComment}\{$Whitespace)"
    # * EndRegex ```$whitespace + '}' + $EndComment + $ignoredContext```
    $EndPattern   = "(?<PSEnd>$Whitespace\}${endComment}\s{0,}${IgnoredContext})"
