IMPORTANT: Update several ROMS processing Matlab scripts

[arango]

Several Matlab scripts in various subdirectories were updated or added:

• coastlines: The coastline extract function get_coast.m was updated to select the desired GSHHS dataset. Also, updated r_gshhs.m and x_gshhs.m functions to process newer versions of the GSHHS dataset. It currently process up to version 2.3.6.

• grid: Add new function rotate_grid.m to extract rotated Cartesian (rotate_cartesian.m) or spherical (rotate_spherical) grids. It will be used in the future fon nonalingned uniform refinement grids:

• landmask: Modified several functions to work with newer versions of Matlab. The functions editmask.m and editscope.m were updated to use the m_map mapping package for Matlab. The editing GUI has a different look:

• m_map: Added Rich Pawlowicz (rich@…) awesome mapping package for Matlab; Version 1.4j May 2018. For information on how to use m_map check is the ​user manual. I didn't include the GSHHS dataset. To install the GSHHS dataset follow the ​instructions in the m_map manual.

You have the choice of moving the binary data files to your m_map/private directory or have equivalent links. For example, I have the following links in the private directory.

As yu can see, I am using GSHHS Version 2.3.6, released on August 17, 2016.

• netcdf: Updated check_metadata.m, nc_read.m, and roms_metadata.m. I removed the usage of contains in nc_read.m because it a much newer function and doesn't work with older version of Matlab. However, I love the newer contains function.
