Made some updates based on wpcomposed base project -- changed 'config/wordpress.php' to 'config/wp-config.php' to be more clear what it is (a copy of WP's wp-config.php), figured out how to use composer istallers library to install/maintain our plugins where we want.
Merge branch 'master' into export
Finished writing part of script that deletes items in the database that are not in the config file.
Renamed export file to be more specific to what it does.
Updated wpcomposed files according to:
https://github.com/johnshopkins/wpcomposed/commit/97019e6bebeae03e5909d35afd726b11756365bd
Updated advanced custom fields to 4.2 (yay it works now) and added array_column lib.
It's not necessary to change the ABSPATH since we're fooling WP into thinking our config file is where it wants it.
Wrote  command that exports advanced custom form field group settings.
Preliminary import script written.
Fixed getPostMeta() to take into account that some meta items have more than one item in the array.
Exporting only published ACF form groups.
The 'rule' meta attached to field groups is handled in a strange way -- instead of each rule being part of an array on a single 'rule' meta, each rule is stored separately in a 'rule' meta (there are duplicate rule keys). This means that we need to treat the 'rule' meta on ACF posts differently (ugh)
Fixed problems that were causing fields to not be updated in DB properly.
Added documentation, moved thigns around.
Deleted posts from the DB that do not exist in the config.
