Simplifies to build parse types based on the parse module
Description
"parse_type" extends the "parse" module (opposite of
"string.format()") with the following features:
* build type converters for common use cases (enum/mapping, choice)
* build a type converter with a cardinality constraint (0..1,
0..*, 1..*) from the type converter with cardinality=1.
* compose a type converter from other type converters
* an extended parser that supports the CardinalityField naming
schema and creates missing type variants (0..1, 0..*, 1..*) from
the primary type converter
Python 2 version.
