Update docs for KIM

[CMake build]:

-D DOWNLOAD_KIM=value    # download OpenKIM API v1 for build, value = no (default) or yes

-D KIM_LIBRARY=path      # KIM library file (only needed if a custom location) 

-D KIM_INCLUDE_DIR=path  # KIM include directory (only needed if a custom location) :pre

-D DOWNLOAD_KIM=value           # download OpenKIM API v1 for build, value = no (default) or yes :pre

If DOWNLOAD_KIM is set, the KIM library will be downloaded and built

inside the CMake build directory.  If the KIM library is already on

your system (in a location CMake cannot find it), KIM_LIBRARY is the

filename (plus path) of the KIM library file, not the directory the

library file is in.  KIM_INCLUDE_DIR is the directory the KIM include

file is in.

your system (in a location CMake cannot find it), set the PKG_CONFIG_PATH

environment variable so that libkim-api-v2 can be found.

[Traditional make]:

make lib-kim args="-b -a Glue_Ercolessi_Adams_Al__MO_324507536345_001"  # ditto plus one model

make lib-kim args="-b -a everything"     # install KIM API lib with all models

make lib-kim args="-n -a EAM_Dynamo_Ackland_W__MO_141627196590_002"       # add one model or model driver

make lib-kim args="-p /usr/local/kim-api" # use an existing KIM API installation at the provided location

make lib-kim args="-p /usr/local/kim-api -a EAM_Dynamo_Ackland_W__MO_141627196590_002" # ditto but add one model or driver :pre

make lib-kim args="-p /usr/local" # use an existing KIM API installation at the provided location

make lib-kim args="-p /usr/local -a EAM_Dynamo_Ackland_W__MO_141627196590_002" # ditto but add one model or driver :pre

:line

The atom style defined does not have these attributes. :dd

{KIM neighbor iterator exceeded range} :dt

This should not happen.  It likely indicates a bug

in the KIM implementation of the interatomic potential

where it is requesting neighbors incorrectly. :dd

{KOKKOS package does not yet support comm_style tiled} :dt

Self-explanatory. :dd

{Unrecognized virial argument in pair_style command} :dt

Only two options are supported: LAMMPSvirial and KIMvirial :dd

{Unsupported mixing rule in kspace_style ewald/disp} :dt

Only geometric mixing is supported. :dd
