@subsection TokenRateChange Enables detection of properties for CIC tokens that change value over time, e.g. through demurrage. It allows defining the granularity of the rate of change, aswell as a frequency for which the rate of change is applied. A method for canonical value change calculations is also provided. @subsubsection ERC165 Interface identifier @include ../../build/TokenRateChange.interface @subsubsection Solidity interface definition @include ../../build/contract_TokenRateChange.texi @subsubsection Reference implementations @itemize @item @uref{git://holbrook.no/erc20-demurrage-token.git,} @end itemize
