Rollout

Version 1.0 is a good time to fix minor mistakes in design, even if they break compatibility. These are proposed changes, to be made in the v1 branch.

apop_name struct

• change column to col [done]
• change title from char [101] to char * [done]

apop_data struct

• Deprecate all the apop_data(get|set|ptr)_(ti|it|tt|ii) functions; use apop_data_get, apop_data_set, and apop_data_ptr only

apop_model struct

• Change p and log_likelihood return valuess to long double, not double. Especially for p, the precision matters.
• Remove Apop_settings_alloc
• Rename Apop_model_add_group to Apop_settings_add_group.
• Change name from char [101] to char *
• Remove score, predict and parameter_model; implement using the vtable mechanism
• estimate method can return void, saving a line of code everywhere. Note again that the prep method makes a copy of the model.

apop_opts struct

• Deprecate many global options that have no business being global: apop_opts.output_delimiter ? apop_opts.input_delimiters apop_opts.db_nan apop_opts.db_user/pass

Functions and macros

• Apop_row should produces a full data set, not a vector as it does now. That is, rename Apop_data_row to Apop_row.
• apop_data_add_named_elmt should write to the vector (as it once did), thanks to the DWIM exception added to apop_get, apop_set, &c. [i.e., given a data set with no matrix and a vector set up with the post-revision apop_data_add_named_elmt, apop_data_get(result, .rowname="xx") will get the vector element in the given row; before it searched the matrix.] This affects where many model coefficients get written.
• Model coefficients with common Greek names [μ, σ] should be labelled as such, not via English-language spellings of those names.
• Deprecate apop_line_to_data.
• for apop_mle, trace_path should produce a matrix, not write to the db.
