0.1b7

• Transferred repository to NMNH-IDSC
• Added from_xml_parallel() method to EMuReader to allow parallel reading of XML files (experimental)
• Added support for pickle and json to EMuRecord objects
• Added check for missing grid fields to the EMuReader and EMuGrid objects. These methods are intended to allow users to catch when a required grid field is missing from an export.
• Changed custom data types to be essentially immutable. Previously attributes could be directly modified.
• Changed loading of schema and config files such that these files are explicitly loaded when the module is imported. Previously they were lazy loaded when an associated attribute was accessed.
