Enable transform _sample_curve to work with VariableFactory

[lucianopaz]

Description

The core problem was that the transform's _sample_curve method created a Model instance that didn't have access to all of the required coordinate information. The secondary issue that I addressed was to automatically determine the expected core dimensions of the transformation's output. The way this used to work was very brittle because it relied on expecting the function_parameters to be stored in the parameters dataset. The method I used just relies on the meta information of the parameters' dims.
