.Synopsis
1337+
Tests the meta file integrity of the Unity Project Instance(s).
1338+
.DESCRIPTION
1339+
Tests if every item under assets has an associated .meta file
1340+
and every .meta file an associated item
1341+
and that none of the meta file guids collide.
1342+
.PARAMETER Project
1343+
Unity Project Instance(s) to test the meta file integrity of.
1344+
.PARAMETER PassThru
1345+
Output the meta file integrity issues rather than $true (no issues) or $false (at least one issue).
1346+
