Split list of source and header files in a vertical column
Changed time_mape_get_size() to return actual size - and not last_step
Removed implementation/type enkf_plot_arg_type
Cleaned up implementation enkf_plot_member
Renamed enkf_plot_member -> enkf_plot_tvector
Renamed enkf_fs_open() -> enkf_fs_mount()
Renamed enkf_fs_close() -> enkf_fs_umount()
Added refcount on enkf_fs instances:

  - Removed function enkf_main_umount_alt_fs() completely.
  - Every fs mount should be matched up with an enkf_fs_umount(); this
    includes the enkf_main_mount_alt_fs() function.
  - enkf_fs_unmount() will decrease ref, and close+++ when ref==0.
Simplified the enkf_plot_data implementation
Added enkf_plot_data test based on an existing test Storage/ directory
Cleanups of enkf_plot_data / enkf_plot_tvector.c
Merge branch 'enkf_fs_refcount' into plot-data-type
Will not sync readonly fs when closing
More plot_tvector
Merge remote-tracking branch 'joaho/plot-data-type' into plotting
Added missing test file
Merge branch 'enkf_fs_refcount' into plot-data-type
Merge remote-tracking branch 'joaho/plot-data-type' into plotting
Added missing include
Fixed typo
