/// @assertion int memLevel
/// final
/// Specifies how much memory should be allocated for the internal compression
/// state. 1 uses minimum memory but is slow and reduces compression ratio; 9
/// uses maximum memory for optimal speed. The default value is 8.
///
/// The memory requirements for deflate are (in bytes):
///
/// (1 << (windowBits + 2)) + (1 << (memLevel + 9))
/// that is: 128K for windowBits = 15 + 128K for memLevel = 8 (default values)
/// @description Checks that this property returns constructor's memLevel
/// argument
