Creates an OEMatchField object to be used for adding data to, or retrieving data from, an OERecord object. Match fields are used mainly to retrieve data from a record when you don’t know the name of a field but know its type and associated metadata.

name: The name the field will be given.
t: This specifies the type of match field to be created. This will usually come from the Types namespace.
meta: If this field is provided, the returned OEMatchField object will only retrieve data from fields that match this metadata.
readonly: If true, the returned match field can only be used to read data to a record, not write it.
nullable: If true, the returned field match field will allow setting of null values on a record.
