method to estimate base request size #263
expose data types on dimension objects #265

Added dimension sizes to the dictionary return. The mapping has
changed. Also need to add a dtype property to the VectorDimensions.
This required some modifications to the inheritance structure.

Closes #263.
Closes #265.
vector_wrap option causes mismatch between field and collection geometry #267

Moved some example files around and added a check to make sure the
geometry is correctly inserted into the collection. The issue occurs
when 0 to 360 longitudinal data is used and vector_wrap is True. Now
the geometry is appropriately copied in subset.

Closes #267.
handling of "point" spatial abstraction #214

Point abstraction is now used for operations even if overload and
bounds/polygons are available.
added new examples and minor mods to logging messages
do not append variable name to calculation names #268

Changes to calc/base allowing function classes to overload how
the derived variable alias is determined. The target variable
alias is not appended in the case of a univariate calculation over
one variable. It is appended if the calculation is applied to multiple
variables. Tests were updated for the new case.

Closes #268.
do not append variable name to calculation names #268

Fixed tests.
shp_scanner geometry filtering

Allowed filtering of geometry with an actual dataset as opposed to
geometries.
prototype integration with external climate indices library #238

This contains a working implementation for the ICCLIM library. Major
indice categories are covered. Also contained in this commit are
changes to "large_array.compute" to handle a wider range of operations
conditions.
method to estimate base request size #263

Added shapes and data types to the method. The structure of the
output dictionary changed slightly. These changes are documented.
allow two-way transformations between rotated pole and wgs84 #271

Writing to netCDF following a subset or calculation has been enabled
for rotated pole. There are limitations with this coordinate system
for other output coordinate systems besides WGS84.
additional functions added to subset

Geometry processing was explicitly added as a function in subset.
updated symbols following ICCLIM reorganization
