- Updated the name and description of the Hilbert Trendline (HTIT) to "Ehlers Hilbert Transform Instantaneous Trend (HTIT)". - Changed the name and description of the MESA Adaptive Moving Average (MAMA) to "Ehlers MESA Adaptive Moving Average". - Modified the Center of Gravity (CG) indicator to "Ehlers Center of Gravity (CG)". - Renamed the Detrended Synthetic Price (DSP) to "Ehlers Detrended Synthetic Price (DSP)". - Updated the Autocorrelation Periodogram (EACP) to "Ehlers Autocorrelation Periodogram (EACP)". - Changed the Homodyne Discriminator (HOMOD) to "Ehlers Homodyne Discriminator (HOMOD)". - Updated the Hilbert Transform Dominant Cycle Period and Phase indicators to include "Ehlers" in their names. - Renamed the Hilbert Transform Phasor Components to "Ehlers Hilbert Transform Phasor Components (HT_PHASOR)". - Updated the SineWave indicator to "Ehlers Hilbert Transform SineWave (HT_SINE)". - Changed the Phasor Analysis indicator to "Ehlers Hilbert Transform Phasor Components (HT_PHASOR)". - Updated the SSF-Based Detrended Synthetic Price to "Ehlers SSF Detrended Synthetic Price (SSFDSP)". - Renamed the Ultimate Channel to "Ehlers Ultimate Channel (UCHANNEL)". - Added new indicators: Moving Average Variable Period (MAVP), Ehlers Predictive Moving Average (PMA), Ehlers Reverse EMA (REVERSEEMA), and Ehlers Trendflex Indicator (TRENDFLEX). - Updated various SVG badges to reflect changes in classes, comments, source files, lines of code, methods, and public types.
