1. Move the implementation of OWSearch() into OneWireMaster since it is a fairly complex algorithm that shouldn?t be implemented over and over. It will also match all other ROM function that are implemented there.
2. Create a new member function, OWTriplet(), in OneWireMaster to handle the virtual section of OWSearch(). Create a default implementation of OWTriplet() that uses OWReadByte() and OWWriteByte(). Masters only need to implement this function if they have a search accelerator of some sort.
3. Create type SearchState that will encapsulate all persistent data used by the search ROM functions. This will also make it easy to not have the search state part of the permanent OneWireMaster class data.
4. Rename OWSpeed() to OWSetSpeed() and OWLevel() to OWSetLevel() for naming consistency.

j3 | 1:91e52f8ab8bf | 243 | * @details Use the Ds248x help command '1-Wire triplet' to perform |
j3 | 1:91e52f8ab8bf | 244 | * one bit of a 1-Wire search. This command does two read |
j3 | 1:91e52f8ab8bf | 245 | * bits and one write bit. The write bit is either the |
j3 | 1:91e52f8ab8bf | 246 | * default direction (all device have same bit) or in case |
j3 | 1:91e52f8ab8bf | 247 | * of a discrepancy, the 'search_direction' parameter is |
j3 | 1:91e52f8ab8bf | 248 | * used. |
