/*
 * ModuleInstaller - takes an installation package from files in the custom/Extension/X directories, and moves them into custom/X to install them. 
 * If a directory has multiple files they are concatenated together. 
 * Relevant directories (X) are Layoutdefs, Vardefs, Include (bean stuff), Language, TableDictionary (relationships)
 * 
 * Installation steps that involve more than just copying files:
 * 1. installing custom fields - calls bean->custom_fields->addField
 * 2. installing relationships - calls createTableParams to build the relationship table, and createRelationshipMeta to add the relationship to the relationship table
 * 3. rebuilding the relationships - at almost the last step in install(), calls modules/Administration/RebuildRelationship.php
 * 4. repair indices - uses "modules/Administration/RepairIndex.php";
