Keyboard Layout Templates

This is so that the function can be called here, and replaced in the `secrets.c` file, and so it won't error out if it doesn't exist.
And then, in the `process_record_user` function, assuming you have `return process_record_keymap(keycode, record)` here, you'll want to replace the "final" return with the following. Otherwise, you want to replace the `return true;` with `return process_record_secrets(keycode, record);`
Here, you want your `/users/<name>/rules.mk` file to "detect" the existence of the `secrets.c` file, and only add it if the file exists. To do so, add this block:
```c
```make
ifneq ("$(wildcard $(USER_PATH)/secrets.c)","")
SRC += secrets.c
endif
```
Additionally, if you want to make sure that you can disable the function without messing with the file, you need to add this to your `/users/<name>/rules.mk`, so that it catches the flag:
```c
```make
ifeq ($(strip $(NO_SECRETS)), yes)
OPT_DEFS += -DNO_SECRETS
endif

Then, if you run `make keyboard:name NO_SECRETS=yes`, it will default to the test strings in your `<name>.c` file, rather than reading from your file.
Userspace EEPROM config
-----------------------
This adds EEPROM support fo the userspace, so that certain values are configurable in such a way that persists when power is lost. Namely, just the clicky feature and the Overwatch macro option ("is_overwatch"). This is done by reading and saving the structure from EEPROM.
To implement this, first you need to specify the location:
```c
#define EECONFIG_USERSPACE (uint8_t *)20
```
This tells us where in the EEPROM that the data structure is located, and this specifies that it's a byte (8 bits). However, to maximize it's usage, we want to specify a data structure here, so that we can use multiple settings. To do that:
```c
typedef union {
uint8_t raw;
struct {
bool clicky_enable :1;
bool is_overwatch :1;
};
} userspace_config_t;
```
Then, in your C file, you want to add: `userspace_config_t userspace_config;`, and in your `matrix_init_*` function, you want to add `userspace_config.raw = eeprom_read_byte(EECONFIG_USERSPACE);`
From there, you'd want to use the data structure (such as `userspace_config.is_overwatch`) when you want to check this value.
And if you want to update it, update directly and then use `eeprom_update_byte(EECONFIG_USERSPACE, userspace_config.raw);` to write the value back to the EEPROM.
