Subject: [PATCH] Add copright, and better documentation to curves.pl

The purpose and use of the test script, curves.pl was not obvious without
reading the source code, plus the file was missing a copyright statement.

+# Purpose
+#
+# To test the code dependencies on individual curves in each test suite. This
+# is a verification step to ensure we don't ship test suites that do not work
+# for some build options.
+#
+# The process is:
+#       for each possible curve
+#           build the library and test suites with the curve disabled
+#           execute the test suites
+#
+# And any test suite with the wrong dependencies will fail.
+#
+# Usage: curves.pl
+#
+# This script should be executed from the root of the project directory.
