Add script for re-compiling fmu files

docs/scripts/recompile_fmu.sh

+#!/usr/bin/env bash
+
+# This script re-compile all *.fmu files in the current directory using
+# current available c++ compiler. This makes the fmu files compatible with
+# the host OS.
+
+# For example if you have .fmu files exported from ModelicaEditor running
+# in Windows but you need linux version. To make these .fmu files compatible
+# with linux, you should:
+#   1. import and re-export the Windows version .fmu files using linux ModelicaEditor
+#   2. copy this script in the same directory where the re-exported .fmu files are located
+#   3. run this script with ./recompile_fmu.sh
+#   4. all .fmu files should be re-compiled and compatible with linux
