DOC: Fix reconst_mapmri example markup.

[jhlegarreta]

Fix formatting issues in the reconst_mapmri file to get the
documentation correctly rendered in:
http://nipy.org/dipy/examples_built/reconst_mapmri.html#example-reconst-mapmri

Changes:

• Indent lists properly.
• Indent literal blocks properly.
• Remove unnecessary double quotes for indented code/literal blocks.
• Use double backquotes for inline code samples.

[jhlegarreta]

Any ideas as to why the following code block is not correctly rendered?

We can then fit the MAPMRI model to the data.

::
    mapfit_laplacian_aniso = map_model_laplacian_aniso.fit(data_small) mapfit_positivity_aniso =
 map_model_positivity_aniso.fit(data_small) mapfit_both_aniso = map_model_both_aniso.fit(data_small) 

And why the RTOP figures are all black (dynamic range issues?)

Thanks.

Any ideas as to why the following code block is not correctly rendered?

I think this has been corrected here. A "space" was missing.

And why the RTOP figures are all black (dynamic range issues?)

No idea for the moment

[skoudoro]

can you rebase this one too @jhlegarreta? thank you

[jhlegarreta]

@skoudoro Sure. b4eb160 was rebased on master.

[jhlegarreta]

@skoudoro Codecov reports a decrease in the coverage but this is only a documentation change, so I think this is ready to be merged

[skoudoro]

Sorry for the delay @jhlegarreta, I agree, it is ready to be merged, can you rebase and I can do it when it is done.
Thank you

[jhlegarreta]

No worries @skoudoro. 1bee094 was rebased on top of master.

[skoudoro]

Thank you @jhlegarreta, merging !
