=head1 NAME
Data::Frame::Types - Custom Type::Tiny types
=head1 VERSION
version 0.006004
=head1 DESCRIPTION 
This module provides custom types and coercions from the Data::Frame
project.
Types:
=for :list
* DataFrame
* Indexer
* ColumnLike
This is basically piddle of 0D and 1D.
* Column
Now it's same as ColumnLike, but will likely evolve into a dedicated type
in future.
* DataType
One of the PDL types
C<"ushort">, C<"long">, C<"indx">, C<"longlong">, C<"float">, C<"double">,
or C<"string"> (PDL::SV), C<"factor"> (PDL::Factor),
C<"logical"> (PDL::Logical), C<"datetime"> (PDL::DateTime).
Coercions:
=for :list
* IndexerFromLabels
* IndexerFromIndices
