<p>Changes (by Roland Haas):</p>
<p>Allow setting parameter values at build time, enabling additional compiler optimisations. I measured that e.g. ML_BSSN runs 5% to 10% faster if its parameters are chosen at build time.</p>
<p>This introduces macros <code>CCTK_PARAMETER__${thorn}__${parameter}</code>. If unset, the parameter value is taken from the parameter file (default). If set at compile time, e.g. via a -D option in <code>CPPFLAGS,</code> this overrides the parameter database, and <code>DECLARE_CCTK_PARAMETERS</code> will always use this value.</p>
