* present on the given mesh.
* * Example:
* @code
* PolyMesh m;
* if (hasProperty<FaceHandle, bool>(m, "is_quad")) {
* // We now know the property exists: getProperty won't throw.
* auto is_quad = getProperty<FaceHandle, bool>(m, "is_quad");
* // Use is_quad here.
* }
* @endcode
* @param mesh The mesh in question
* @param propname The property name of the expected property
* @tparam ElementT Element type of the expected property, e.g. VertexHandle, HalfedgeHandle, etc.
* @tparam T Value type of the expected property, e.g., \p double, \p int, etc.
* @tparam MeshT Type of the mesh. Can often be inferred from \p mesh
